Boot from USB is not working #593

Closed cps12145 closed 7 years ago

cps12145 commented 7 years ago

So I have two different USBs. When I put one in my old laptop before they had an OS on them, the BIOS would actually pick up the USB, and allow me to boot from it. That obviously didn't work because there was no OS on it yet. Once I burned the ISO to them, and entered either one into my old laptop, the BIOS would nolonger pick it up. What's going on here? What am I doing wrong?

UPDATE! I enabled Legacy in the BIOS, and I got the USB to start to boot, however, the screen is stuck with the text "Finding PCI Devices SYSLINUX 4.07 EDD (copyright stuff blah blah) Loading Cosmos.bin... ok" And it's stuck there with the flashing text cursor. What should I do?

Probably this is the same as #370.

Thank you.

I tried to boot on a different computer, and it booted up just fine. The only thing is that it's having some trouble with filesystem. I'm getting this http://imgur.com/a/Njot4

Does it have a FAT partition?

cps12145 commented 7 years ago

Not the computer. The USB does.

cps12145 commented 7 years ago

I got no errors about it finding an FAT filesystem. I listed the volumes and 0:\ showed up using FS.getvolumes.

jp2masa commented 7 years ago

The computer needs to have a FAT partition, we don't have USB support.

jp2masa commented 7 years ago

Maybe you're using a GPT partition scheme, they are not supported. https://github.com/CosmosOS/Cosmos/wiki/FAT-FileSystem#warnings

cps12145 commented 7 years ago

Oh. I thought I saw someone say that when on a bootable drive, the ISO just uses it as the hard disk.

@cps12145 do you have debugging on???

cps12145 commented 7 years ago
